Another phenomena, similar to qwertyuiopasdfghjklzxcvbnm, that happens to a computer's keyboard when a human being is bored to death, but instead of pressing the keys in a west-east direction, said human being decides to type them in a snake-like pattern, starting from the top row, right corner going left then from the middle row, left corner going right and finally from the bottom row, right corner going left.
Ugh, I'm so bored, I guess I'll be poiuytrewqasdfghjklmnbvcxz
When we are soooo... bored, then we type qwertyuiopasdfghjklzxcvbnm and bored with that also, then we go reverse qwerty and then reverse it and type the both side of keybord qazplm

This is when you absent-mindedly run your finger along the keys, left to right, then right to left... Being careful not to press delete, enter or tab. The phenomena usually occurrs when you are so bored you really don't know what else to do...
